As Paul says...there are many new experiments
The point is that we have synthesized the amino acids. Nature took many millions of years to get from basic chemicals to recognizable life forms. All that is necessary to know in order to make the theory feasible is that we know the building blocks were there and that we HAVE replicated the 1st steps.

Don't forget, Pete, that claiming a 'creator' doesn't even begin to answer why or how such a thing happened. Even science doesn't know "why there is something, rather than nothing".... but all religion does is ignore the question and assert an answer.... and I'm afraid that "God says He did it." doesn't carry much weight when one book written by men is the only data.
